react-native example error

Connection to localhost port 8081 [tcp/sunproxyadmin] succeeded!
Port 8081 already in use, packager is either not running or not running correctly
Command /bin/sh failed with exit code 2

端口8081被占用。

$ Movies git:(master) lsof -i:8081

还发现一种可以改变react native 监听端口的方法。

1. cd project-dir && react-native start --port 8889；
2. 到xcode里面search所有的8081，将它们替换为8889；
3. xcode找到 Libiaries/React.xcodeproj/Build Phases/Run Scripts. 替换8081.
4. run it.
